Fertilization cart

Abstract

Disclosed is a fertilization cart, including a hopper for containing the fertilizer, a first turntable, and a second turntable, where the first turntable and the second turntable are located below the hopper and arranged in correspondence with discharge openings on the hopper. Spreader openings are formed on either of the first turntable and the second turntable, and when the spreader opening is communicated with the discharge opening after rotating, a spreader channel is formed. The first turntable is capable of rotating relative to the hopper to open or close the spreader channel. The second turntable is capable of rotating relative to the first turntable to adjust the size of the spreader channel. The present disclosure is capable of solving the technical problem in the prior art that the fertilization cart cannot accurately control the amount of fertilizer for different vegetation.
